RAILWAY SNOW-PLOW.

Specification of Letters Patent.

Patented Jan. 29,1907.

Application filed June 28. 1906. $erial No. 323,920.

To all whom, it may concern.-

Be it known that I, NELS HILL, a citizen of the United States, residing in Sykeston, in the county of Wells and State of North Dakota, have invented certain new and useful Improvements in Railway Snow-Flows, of

which the following is a description, reference being had to the accompanying drawings.

My invention relates .to improvements in railway snow-plows; and the object of my invention is to provide a'snow-plow of simple construction and efficient operation.

In the drawings illustrating the principle of my invention and the best mode now known to me of applying that principle, Figure 1 is a side elevation of my new snowplow. Fig. 2 is a plan view of the same, and Fig. 3. is a front end view of the same.

The wheels at of the trucks 1), Figs. 1 and 3, are provided with a sharp flange c, which enables them to cut through the snow, and thereby prevents the wheels being forced off the track. Upon the trucks 1) is mounted the body 6 of an ordinary fiat-car, upon the rear end of which is a cab 61 and upon the front end of which is a scoop f, which inclines downwardly and to the front, so as to out close to the rails. The scoop f is provided with side knives g and with intermediate cutters h, Fig. 2, which serve to cut up into small chunks any snow which may be packed solidly, as in a drift. The path cut by the side knives g is of sufficient width to insure the ready passage of the train.

Pivotally connected with the scoop f by the bolt 2' is a funnel or chute j, which is made up of sections pivotally secured together, as shown in the drawings. This sectional construction gives to the funnel a certain flexibility which tends to avoid jamming of the snow in the funnel. The funnel j is provided with an upwardly and forwardly projecting mouthpiece is, over which is fitted a movable hood 2, the latter being formed with slots 3, through which project studs 4 from the mouthpiece k. To adjust the hood 2, a pair of right and left hand screws 5,is provided, one end of which engages a threaded lug 6 on the hood and the other end of which engages a threaded lug 7, fast upon the mouthpiece it. By varying the position of the hood 2 the amount of suction of the air up through the chute or funnel 9' may be varied. If the plow is run into a snow-drift, the position of the hood 2 may be changed so as to avoid all wedging action.

The funnel rests upon the cross-bar 'm, supported by the standards n, mounted one on each side of the car-body c. To move the funnel from side to side of the cross-barm, the following mechanism is provided: Mounted on the body'c are a pair of standards 0, which support a shaft 2), to which is secured a wormwheel g, which meshes with a worm 1 on the end of a shaft 8, extending back into the cab (Z and provided with a hand-wheel t. (See Figs. 1 and 2.)

Upon each end of the shaft 2) is a drum u, around which is wound a cord 1), one end of which is secured to the drum and the other end of which is secured to the opposite side of the funnel j, Fig. 2. The cords o are wound in opposite directions upon their respective drums, so that as the shaft 8 is rotated the cord will be wound upon one drum and paid off from the other drum a like amount. Each cord. runs through a block or sheave w, mounted on one of the standards a. By turning the hand-wheel t the operator is able to shift the discharge end of the funnel, so that the snow will be thrown with the wind and not against it.

My new snow-plow is automatic in action, a current of air being directed up through the chute of such strength as to clear the chute and throw the snow far from the track.

What I claim is I 1. In a railway snow-plow, the combination of a car; a scoop mounted thereon; a funnel mounted on said car and free to swing from side to side thereof, said funnel being provided with a mouthpiece which projects outwardly over said scoop; and means for swinging said funnel.

2. In a railway snow-plow, the combination of a car," a scoop mounted thereon; a funnel mounted free to swing on said car and provided with an outwardlyprojecting mouthpiece; and a hood mounted free to slide on said mouthpiece lengthwise of said car.

3. In a railway snow-plow, the combination of a car; a scoop provided with cutters intermediate its sides; a funnel extending up wardly'and rearwardly from said scoop and pivotally secured thereto and provided with a mouthpiece extending outwardly over said scoop; and means for shifting said funnel.

I 4. In a railway snow-plow the combina tion of a car; a flexible funnel made up of several sections pivotally secured together; and a scoop pivotally secured to which is the forward section of said funnel.

5. In a railway snow-plow, the combination of a car provided with a cab near one end thereof; a scoop mounted at the other end of said car; a funnel mounted free to swing on said car from side to side thereof; and mechanism operable from said cab for swinging said funnel said mechanism comprising a Windlass; cords secured to said funnel and Windlass; and means for rotating said Windlass.

6. In a railway snow-plow, the combination of a car; a scoop mounted thereon; a funnel mounted free to swing on said car; a Windlass mounted on said car; and cords con nected with said funnel and Windlass.

In testimony whereof I hereunto set my hand, in the presence of two witnesses, this 22d day of June, 1906.

NELS HILL.
